BIOS Setup

4-30

LARGE mode

This is an extended HDD access mode supported by the Award Software.

Some IDE HDDs contain more than 1024 cylinder without the LBA sup-
port (in some cases, user do not want LBA). The Award BIOS provides
another alternative to support these kinds of HDD.

Example of LARGE mode:

CYLS. HEADS

SECTOR MODE

1120

16

59

NORMAL

560

32

59

LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than
1024 by dividing it by 2. At the same time, the number of heads is
multiplied by 2. A reverse transformation process will be made inside
INT13h in order to access the right HDD address.

Maximum HDD size:

no. Cyclinder

( 1024)

x no. Head

( 32)

x no. Sector ( 63)
x bytes per sector

( 512)

1 Gigabytes

(3) Remarks

To support LBA or LARGE mode of HDDs, there must be some software

involved. All these software are located in the Award HDD Service
Routine (INT 13h). You may not be able to access a HDD with LBA
(LARGE) mode selected if you are running under an Operating System
which replaces the whole INT 13h.
